The conference is organised annually by the Faculty of Economic Sciences of the University of Warsaw in cooperation with the Center for Economic Analysis (CenEA). The keynote lectures were given by: prof. Orazio Attanasio<\/strong> (University College London and Institute for Fiscal Studies) \u2013 Human Development: Theory, Interventions and Measurement<\/em>, and prof. Ariel Rubinstein<\/strong> (Tel Aviv University and New York University) \u2013 Games, Response Time and Typologies of Players<\/em>.
Five of the IBS economists took part in the conference. Below we publish the main messages from their research and the respective presentations.<\/p>\n\n\n\n

Delegation as a signal: implicit communication with full cooperation<\/a><\/h3>\n\n\n\n

Joanna Franaszek<\/a> presented a principal-agent model of communication with perfectly aligned preferences and severe language frictions in the context of doctor-patient relationship. She demonstrated that when language is limited, a novel channel of communication may arise. In particular, the patient\u2019s decision to delegate the choice of treatment to the doctor becomes a signal of his unobservable preferences. The doctor, upon observing delegation and the patient\u2019s health, not only correctly infers the patient\u2019s preferences, but also adjusts his decision to the patient\u2019s needs. Thus, the final treatment becomes non-monotone in health. (The research was conducted at the European University Institute)<\/em><\/p>\n<\/div>\n<\/div>\n\n\n\n

Does unauthorised digital distribution of comic books displace sales?<\/a><\/h3>\n\n\n\n

Wojciech Hardy<\/a> showed his research on e-readership of comic books in an international sample of comics fans. His results show that the so-called online \u2018piracy\u2019 has become an issue also for the comic book industry. At the same time, the experimental part of the study shows that it is very difficult to incentivize the readers to switch to authorized digital sources \u2013 even if they\u2019re presented with free titles from such services. The potential explanation for this is that comics readers very rarely decide to switch comics formats mid-series and prefer to read whole series in one format. (The results was also presented at the<\/em> 20th International Conference on Cultural Economics<\/a> (Melbourne, 26-29.07.2018).<\/em>

The \u201cFamily 500+\u201d child allowance and female labour supply in Poland<\/a><\/h3>\n\n\n\n

Aneta Kie\u0142czewska<\/a> presented a joint work with Iga Magda<\/a> (IBS) and Nicola Brandt (OECD). She showed that labour force participation rate for mothers of one and  two children might have been on average 2.4 pp higher in the absence of the 500+ benefit. Such an effect is observed for the first year after the introduction of the programme and it strengthened after half a year. The reaction among mothers with lowest educational level was the biggest. The results has been publishes in the IBS Working Paper<\/a>.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Does personality impact the returns to cognitive skills?<\/a><\/h3>\n\n\n\n

Marta Palczy\u0144ska<\/a> talked about her study on the relationships between cognitive skills, personality traits and wages. The results show that personality matters for the individual wages in Poland. Employers reward conscientiousness while neurotic and agreeable individuals earn less. Moreover, neurotic individuals have lower returns to cognitive skills. There are no gender differences in the effects of personality on wages.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Are gender wage gaps different in size between domestic and foreign-owned firms?<\/a><\/h3>\n\n\n\n

Katarzyna Sa\u0142ach<\/a> presented the study conducted together with Iga Magda<\/a>. It turns out that adjusted (\u201cunexplained\u201d) gender wage gaps are significantly higher in foreign-owned firms, compared to domestic ones, especially among these firms that entered the market after the economic transition. What is more, adjusted gender wage gaps in foreign-owned firms are distinguishingly large mainly among better paid workers. For those with the lowest earnings the biggest adjusted gender wage gaps are observed in domestic firms, but the differences between the types of firm ownership are rather small, mainly due to the existence of minimum wage.<\/p>\n<\/div>\n<\/div>\n","protected":false},"featured_media":5369,"template":"","news_type":[308],"class_list":["post-7436","news","type-news","status-publish","has-post-thumbnail","hentry","news_type-conference"],"acf":[],"yoast_head":"\nConference WIEM 2018 - IBS - Instytut Bada\u0144 Strukturalnych<\/title>\n<meta name=\"description\" content=\"IBS presentations at the Warsaw International Economic Meeting 2018 (June 3-5).\" \/>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/ibs.org.pl\/en\/news\/conference-wiem-2018\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Conference WIEM 2018 - IBS - Instytut Bada\u0144 Strukturalnych\" \/>\n<meta property=\"og:description\" content=\"IBS presentations at the Warsaw International Economic Meeting 2018 (June 3-5).\" \/>\n<meta property=\"og:url\" content=\"https:\/\/ibs.org.pl\/en\/news\/conference-wiem-2018\/\" \/>\n<meta property=\"og:site_name\" content=\"IBS - Instytut Bada\u0144 Strukturalnych\" \/>\n<meta property=\"article:modified_time\" content=\"2022-12-30T01:37:46+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/ibs.org.pl\/wp-content\/uploads\/2022\/11\/microphone-704257_640.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"640\" \/>\n\t<meta property=\"og:image:height\" content=\"426\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data1\" content=\"5 minutes\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/news\\\/conference-wiem-2018\\\/\",\"url\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/news\\\/conference-wiem-2018\\\/\",\"name\":\"Conference WIEM 2018 - IBS - Instytut Bada\u0144 Strukturalnych\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/#website\"},\"primaryImageOfPage\":{\"@id\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/news\\\/conference-wiem-2018\\\/#primaryimage\"},\"image\":{\"@id\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/news\\\/conference-wiem-2018\\\/#primaryimage\"},\"thumbnailUrl\":\"https:\\\/\\\/ibs.org.pl\\\/wp-content\\\/uploads\\\/2022\\\/11\\\/microphone-704257_640.jpg\",\"datePublished\":\"2018-07-31T02:49:22+00:00\",\"dateModified\":\"2022-12-30T01:37:46+00:00\",\"description\":\"IBS presentations at the Warsaw International Economic Meeting 2018 (June 3-5).\",\"breadcrumb\":{\"@id\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/news\\\/conference-wiem-2018\\\/#breadcrumb\"},\"inLanguage\":\"en-US\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\\\/\\\/ibs.org.pl\\\/en\\\/news\\\/conference-wiem-2018\\\/\"]}]},{\"@type\":\"ImageObject\",\"inLanguage\":\"en-US\",\"@id\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/news\\\/conference-wiem-2018\\\/#primaryimage\",\"url\":\"https:\\\/\\\/ibs.org.pl\\\/wp-content\\\/uploads\\\/2022\\\/11\\\/microphone-704257_640.jpg\",\"contentUrl\":\"https:\\\/\\\/ibs.org.pl\\\/wp-content\\\/uploads\\\/2022\\\/11\\\/microphone-704257_640.jpg\",\"width\":640,\"height\":426},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/news\\\/conference-wiem-2018\\\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Conference WIEM 2018\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/#website\",\"url\":\"https:\\\/\\\/ibs.org.pl\\\/en\\\/\",\"name\":\"IBS - Instytut Bada\u0144 Strukturalnych\",\"description\":\"Jeste\u015bmy niezale\u017cn\u0105 fundacj\u0105 naukow\u0105.
